Abstract: The present invention concerns a mechanical watch (1), preferably of the pocket watch type, wound by a key. More specifically, the present invention concerns a protective device for the aperture (6) allowing access to the winding mechanism of such a watch, particular to the winding stem (7). For this purpose, a moving element (8) is implemented, mounted around the stem (7) and able to move between two end positions, first of all to at least partially block the aperture (6) in normal use and, secondly, to release access to the winding stem (7) in order to wind the watch.

Abstract: The wristwatch of substantially rectangular shape includes two sliding shutter-type covers (6, 7) sliding over a case (1) to show or to conceal said case via manual action exerted on said shutters. The shutters are secured to the case by holding means (9) distinct from the guide means (8), said means being implemented to exert a vertical force (F) under each of the shutters tending to apply said shutters (6, 7) against the holding means (9) to reduce the shutter friction surface on the case.
